BOLAGET SVENSKA KULLAGERFABRIKEN, or GOTTENBORG, SWEDEN, A Conro- BOGIE FOR RAILWAY CARS AND THE'LIKE.

Application filed January 18, 1926, Serial No. 81,904, and in Sweden January 21, 1925.

a The present invention relates to improve ments in bogies or trucks for railway cars and the like, in which theload is transmitted tothe beam supported by; the journal boxes by a spring restmgiin a Socket on theupper side of the beam,] the invention consisting essentially in formingthe spring receiving socket as a vertically disposedhole, prefer ably of c lindrical outline,- passing entirely throu h t e beam from the upper to the lower side or enabling the, introduction of the a spring from the lower side of the beam.

The various details of carrying out the preferred form of mounting and the inclental formation of the various parts are described in detailin connection with the drawings.

In the cation ,one embodiment of the invention is illustrated, in which drawings,

Fi re 1 is a side elevation of a portion of a railway truck embodying the preferred form of my invention. I

Fig. 2 is a planpartly in section of the journal box and a portion of the beam suspended therefrom.

Fig. 3 is an enlarged sectional view showing a portion of the invention and Fig. 4 is an underside of the lower plate shown in Fig. 3, the screw bolt being shown in section.

In the form of embodiment shown which illustrates but one of the journal boxes, journal box, 1, is provided with an outward projection, 2, upon which the beamis suspended by a suitable joint. A coiled spring, 4, 1s shown resting upon the beam, 3, and supportf ing the truck frame, 5. v

The spring, 4, is shown seatedin-a socket, 6, which is in the form of a cylindrical hole passing vertically through the beam from its upper to its lowerside. The s ring is shown resting upon a lower plate, which constitutes, when in place, the bottom of the socket, the bottom of the socket being shown provided with segmental shoulders, 10, and plate, 7,' having corresponding recesses, 9, whereby the plate may be introduced from below, the shoulders, 10, passing through recesses,9, whereupon aquarter turn will cause the plate to rest upon the shoulders,10, this constituting a form of bayonet-lock. In the illustration the plate, 7, is: shownprovided' with downwardly projecting lugs, 11, for en drawings accompanying this appli gaging the ends ofthe shoulders, 10, for

preventing rotation and accidental displacement of the plate. 7 I The upper end of the spring, 4, bears against a bracket, 13, suitably secured to the truck frame, 5, and which is provided with a'down'wardly openingrecess or cup, 14."

The spring, 4t, may conveniently be com? pressed before mounting. That is, it is placed between the plate, 8, which is adapted'to enter the cup, '14, and the lower plate,.7,and is compressed by means of the bolt, 12, the head of which is below the lower face of the plate, 7, its screw end passing through the screw threaded opening in the plate, 8. By this means the spring may be suitably compressed on the plate 7 in Fig. 3, whereupon the assemblage is inserted through the lower opening of the socket, 6, and the assembly given a quarter turn to cause the unrecessed portion of the plate, 7, to rest upon the shoulders, 10, with the lugs, 11, projecting downwardly past the ends of the shoulders,

spring.

The removal ofthe spring can readily be accomplished by a reversal of the operation,

it being merely necessary to compress the spring by means of the bolt, 12, raise the lower plate sufiiciently to cause the lugs, 11, to clear the shoulders, 10, give the plate, 7, a quarter turn and lower the spring with the plates t through the open end of the socket, 6.

It will be obvious that various changes in 7 details of construction may be made within the scope of the claims without departing from the spirit of the invention.

Having described my invention I claim and desire to secure by Letters Patent: 1

1. An improvement in trucks for railway cars and the like comprising a journal box, a beam supported by the journal box,such

beam having an upwardly directed socket,

vtirely removed after the mounting of the j for supporting a spring, the socket extending downwardly entirely through the beam,

whereby the spring may be inserted from below, and means for supporting the spring after its insertion. i

2. An lmprovement in trucks for railway cars and the like comprising a ournal box,

a beam supported by the journal box, such beam having an upwardly directed socket for supporting a spring, the socket extending downwardly entirely through the beam, whereby the spring may be inserted from below, the socket being provided with inwardly directed segmental shoulders, and a closure plate having recesses corresponding with the shoulders, constructed and adapted to pass the shoulders and, upon angular movement, rest thereon.

3. An improvement in trucks for railway cars and the like comprising a journal box, a beam supported by the journal box, such beam having an upwardly directed socket for supporting a spring, the socket extending downwardly entirely through the beam, whereby the spring may be inserted from below, the socket being provided with inwardly directed segmental shoulders, and a closure plate having recesses corresponding with the shoulders, constructed and adapted to pass the shoulders, and, upon angular movement, rest thereon, the plate being formed at its lower face with lugs for engaging the ends of the shoulders when in place.

4. An improvement in trucks for railway cars and the like comprising a truck frame, a journal box, a beam supported by the journal box, the truck frame having a downwardly opening spring socket and the beam having an upwardly opening spring socket, such latter spring socket being, formed with inwardly directed segmental shoulders, a closure plate for supporting the spring having recesses corresponding to said shoulders, there being a plate interposed between the top of the spring and the truck socket, and a bolt passing through such plates constructed and adapted to compress the spring for purposes of removal and replacement.

In testimony whereof I have signed my name.

LARS GUSTAF HARRY HELMSTEIN.
